-Aa is supposed to yield ANSI behavior, while -Ae is extended C.
Technically (if HP were following the standards as closely as other vendors),
using -Aa would cause problems (since, for example, some of the prototypes
may not match since default promotions don't match, some of the header
definitions wouldn't be visible because they're POSIX rather than ANSI,
etc.).  I'd expect HP-UX 10.x to be a little closer to the standards than
9.x, though (was this also 9.x?).

I'm using autoconf 2.12, with a one-line patch that someone on the net
posted to allow the generated scripts to workaround a shell buffer-limit.
(So 2.12 should work - I stopped using 2.10+patches about a month after
2.12 came out).

right - I'm only testing K&R configure with native curses on SunOS & HP-UX,
just in case someone wants to do that.

I've got online man-pages for Solaris, IRIX and HP-UX (which I think
document these things).  The real issue was whether those special definitions
were needed, since that's the only reason I didn't remove the snake2/snake3
targets yet.
